OKLAHOMA CITY - An Oklahoma City man is accused of making deadly threats against Gov. Mary Fallin.

Police say the suspect, 27-year-old Matthew Johnson, had been outraged over the governor's opposition to legalizing marijuana.

Sgt. Jennifer Wardlow, with the Oklahoma City Police Department, said, "He was upset with the governor due to the fact that marijuana is not legal in the State of Oklahoma and because of that, threatened to kill her."

A search of court records show Johnson has a history of violence, which includes multiple assault charges.

Even one of the suspect's close friends admits Johnson has a temper.

"He's been like this ever since he was a little kid," said James Hugghins. "He just blows up over little things."

It's not clear if Johnson took any steps to actually harm Fallin at the Governor's Mansion or at the Oklahoma State Capitol.

However, just making the deadly threats can be criminal.

James just wishes his friend had been let off with a warning.

Hugghins said, "You know, they could have just said something without taking him to jail, but when they've got death threats, they have to do their job."

For their part, the governor's office reiterated Fallin's opinion on the marijuana issue that sparked the threat by writing, "The governor is opposed to legalizing marijuana because of public safety and health concerns."

When officers showed up to Johnson's apartment, the suspect did not have any weapons and only a single round of ammunition.

Police claim Johnson also threatened to kill any law enforcement officers who tried to stop him from killing the governor.
